Note: EIA collects data on the electric power industry in alternating-current megawatts (MWAC), while IREC and the PV industry in general discusses PV capacity in direct-current megawatts (MWDC), because solar panels produce DC power. For this chart, EIA assumed 80% efficient conversion from DC power to AC power.
